session for 90 minutes done handball exercises. Data analysis by computer using SPSS software and statistical methods of Descriptive and inferential
(ANOVA &-test) was performed. Also the comparison, results of control and experimental groups showed that eight weeks handball exercises had
significant changes on social development and all of aspects of experimental group, except hopefulness and optimism. (a ≥0/05)

Communication and how make relationship with together was the favorite case of the worlds men during the past and now. Man kind always made ready the
way for affairs as the basis of life continuation and by this way man kind could gain their basic needs. In present century which is called
communications century the value and importance of making relation with the world increased by means of a group life and making can yield important
results against difficulties and also exploring the unidentified world. Its important to have true social development means growth of mans behavior in
social relations as can be relevant and have a harmony with his society. A man is social when not only is beside others, but also cooperate with them
[Aliakbar.1995].social growth is the indicator of those abilities that in connection with environment shows us the amount of learning. in the survey of
social development, the purpose is indicate of that how much people can do daily activity of life and social communications[Heshmatollah.1998]. Social development is another kind of growth that its recognition is more
difficult than mental growth [Alice.1997].So it's more important for teenagers and young people who are at the beginning of progress and experience
path. The importance of adolescence period is because of the growth of body forces and also due to expansion of mental potentials that arrives him to
be a social and complete personality. Everything is changing in these years[2].So it should be expanded ,That is a man should be capable to obtain his
independence, responsibility and communication with others as he needs that is gain an acceptable social growth. One of the ways to achieve social
growth is sport exercise with it shows as a healthy way. Team sporting fields like handball can play an important role in social growth. Alinezhad
says: body activity is on of principal elements of the children and teenagers. Body exercises is very effective for expanding of physical performances
like motional skills and power of muscles and physiological potentials and energy production and working feed back and in other hard in children mental
and social growth[Hamid.1997]. Mohammadi in a search by use of Witzmans social growth test and by compare individual athletes with team athletes and
the non athletic students resulted that the team athletes in compare with two other groups have a greater social growth average [Reza.1999].Also vichel
in an article under this title training of social skills by body training writes motion activities and sport. Has a great ability to grow positive
social skills on students [Vigil.1996].And also based on deyvis and his colleae use in the book of psychology and sport, sport and body activity has
social effectiveness [Davise et al. 2000].So researcher try to engage group team exercises to assess amount of social growth and any changes in the
students. In one of sport fields like handball same as other group fields, favorite result occurs when the men in addition to have series of personal
characters like responsibility, should profit from harmonic communications for group actions. So this research wants to study the effect of eight weeks
handball exercises on social development (growth) of male students of intermediate course in khoramshahr, in a case that represents essential
directions to teachers and parents and students.

2. Methods

The method of this research is semi experimental that studies the effect of eight week handball exercises on social development of male students of
intermediate course khoramshahr bye use of pre-test research and post- test and control group.

2.1. Society and statistical sample.

Statistical society of this research consist of 7116 male students 13-18 year old in intermediate course in khoramshahr on education year 2005- 2006.
In this research, sampling is done in randomly case, so khoramshahr town divided in five areas and then selected one school from each area in random
case. Then divided 200 questionnaire randomly among the students of these five schools and so 40 persons who their grades were the least in social
development (growth) at others ratio, were selected as the statistical sample.

2.2. Measurement tools.

From witzoman's social development questionnaire which consist of 27 questions is used for data collecting of this research. Some of the questions have
3 choices and others have 4 choices. This questionnaire shows the amount of social growth since 13 to 18 years old and has four dimensions which are:
self-sufficiency (autonomy), responsibility acceptation, compatibility and communication with others and hopefully. witzman's social development is
made by Ali's witzman. this questionnaire translated to persian by Sima Nazari[Noshabadi.2000].And Abassi has reported the final coefficient of the
questionnaire 0/84 on the teenages 13 to 18 years old in tehran and esfahan cities[Heshmatollah.1998].For final study in this research , kronbakh's
Alfa method was used which it's calculated amount is (r=0/81) in p<0/05 meaningful level. Also Abassi has reported the current coefficient of this
questionnaire on the 13 to 18 years old teenagers in Tehran and Esfahan (r=0/75) which is on the level of p<0/05 meaningful
[Heshmatollah.1998].There are 57 numbers in this questionnaire in all, which based on reply letter and with regard to person's choices, the grade of
0.1.2, 3 was given to the person in each question. Trainee select the best answer based on his idea, after the reading of the question and then marks
it with(X).After the trainees answering, refer to answers key and the grades were given according to selective choice and the general grade calculates
for him.

2.3. Statistical methods.

For data analysis, used from descriptive statistic (mean, standard deviation, tables, diagram…) and deduction statistic (variance analysis and
t-test) which all the statistical operations were done by excel soft ware and SPSS® (version 11.5) with error (fault) modulus of a ≥0/05

3. Results

3.1. Descriptive part of research findings.

Table (1) shows the related data of descriptive statistic of general grades in social growth and its dimensions.

Also the random selection method is used to assign control and experimental group, which the related in formation of (data) to mean and standard
deviation of the grades of social growth and it's dimensions for two experimental and control groups in the per-test said systematically in the
tables(2,3)

Table2: Related grades to social development and its dimensions in experimental group in pre-test

Table3: Related grades to social development and its dimensions in control group in pre-test

3.2. Deduction part of research findings.

In this section the use of deduction statistical methods show there is no meaningful difference between two experimental and control groups because of
social growth and it's dimensions in pre-test on the level of a ≥0/05. Table4.The comparison of the variances of both two groups, shows, there is
no meaningful difference between two groups in per-test.

Table4: F table (comparison of variances) in per-test

In the other hand, to ensure the results of table(4).For comparison of the means of two groups in social development and it's dimensions , T-test is
used which the results in table (5).Shows there is no meaningful difference on the level of a ≥0/05 in per-test between two groups.

Table5: independent t-test, comparison between mean of two groups in pre-test

Since the results of tables four and five show that there is no significant difference between two groups in the level of a ≥0/05 in pre-test. So
in this section, we compare post-test results in two experimental and control groups.

3.2.1.
Table number(6).the results of independent t-test between two groups shows that there is significant difference between two groups in the meaningful
level of p-value=0/000 . Also the results of this table shows well that the mean grades of experiential group are higher , in compare with control
group. After 8 weeks handball exercises. So handball exercises have had a positive effect on the social development variable.

Table6: independent t-test for compare of social development of two groups in post-test

3.2.2.
The data of table number (7).Show that there is significant difference between two groups in the meaningful level of p-value=0/046. Also being high the
mean of autonomy in experimental group shows that handball exercises have had a positive effect on this variable.

Table7: independent t-test for comparison of autonomy of two groups in post-test

3.2.3.
Also The data of table number (8).Shows that there is significant difference between two groups in the meaningful level of p-value=0/000. In other hand
the comparison of the means shows influence of exercise on experimental group. So the results of this theory show that handball exercises could have
positive influence on responsibility.

Table8: independent t-test for comparison of responsibility of two groups in post-test

3.2.4.
The data of table number(9) shows that there is significant difference between two groups on meaningful level of p-value=0/005.Also autonomy mean of
experimental group shows handball exercises have a positive effect on compatibility and make relation.

Table9: independent t-test for comparison of compatibility and relation of two groups in post-test

3.2.5.
The data of table number (10) shows that there is no significant difference between two groups in the meaningful level of P-value=0/290.In fact this
meaningful level shows that handball exercises have no influence on the dimension of hopefulness and optimism.

Table10: independent t-test for comparison of hopefulness and optimism of two groups in post-test

4. Discussion and conclusion

The findings of the research show that eight weeks handball exercises have influence on the sense of male students' autonomy. In other word, the
students' autonomy who takes part in handball exercises was higher than others, meaningfully. It seems the completed researches have done more on
social development from. and we cant find few researches which survey social development dimensions separately, so the results of this research in
compare with stonsons research findings based upon sociality and autonomy by sport is weak or unremarkable a bout autonomy are
disharmonious[Stevenson.1975].incompatibility of this finding with the findings of has done research ,may be for difference in place execution or the
kind of sport field[Heshmatollah.1998].considering that the amount of obtained autonomy from participated students in handball group(team)athletes are
good situations for developing the teenagers and youth autonomy level. Having the sense of autonomy in an acceptable extent has a good results on the
individual life , in a way that person can take regarded decisions in the life with high self-confidence and access to his purpose just based on
self-abilities and without depending on others. Having such men beside each other in a society cause a progressive society.

In this research, the comparison of the sense of responsibility in experimental group and control groups shows that there is a significant difference
between the senses of responsibility in two groups after eight weeks handball exercise. It means responsibility among the students who took part in
handball exercises in compare with others who did not participate in exercises is on higher level. in the researches, responsibility analyze as one of
the dimensions of social development and hasn't studied separately. Any way the results of this variable are the same as many results of other
researchers[Nico .2010].There from peoples responsibility is on of the development particulars in each society, we hope by people participating in
grouped activities, more the society toward development.

The results of comparison compatibility and make relation with others between experimental and control groups after eight weeks showed that there is
significant difference between two groups. In the other word compatibility and make relation with others among the students who participate in grouped
handball exercises in compare with those who haven't participated are in a higher level. That these findings have harmony with other findings of
researches[Daniel et al.2010., Marilyn .2009., Richard et al .2009., Laura et al.2009., Elizabeth et al 2009., Sam.2008., Gregory.2008., Philip et
al.2007., Michael et al 2005., Michael et al .2000., ]

the results of comparison dimension of hopefulness and optimism between experimental and control groups after eight weeks showed that there is no
significant difference between two groups. In the other word hopefulness and optimism of students that participate in handball exercise with those who
didn't participate approximately was the same. These findings have no harmony with many other researches[Nico.2010.,Joseph et al.2007., Snyder et al
.2006.,Suzanne et al.2006.,Cindy et al.2006]. Discordance of this finding with the finding of accomplished research, May be due to reasons like
literacy level, culture and economy of statistical society of this research with other researches.

Also the results of comparison of the total social development in experimental and control group showed that there is a significant difference between
the social developments of two groups after eight weeks handball exercise. It means the students who participated in handball exercise, in compare with
those who didn't participate gregarious exercise, Have a higher social development, meaningfully. This finding has a harmony with findings of many
other researchers[Fruchart et al.2010., David et al .2010., Michael et al.2006., Sarah et al.2009., Şenay et al.2009., Wylleman et al.2009.,
Gillet et al.2009., Mary et al.2009., Homas et al.2009., Eva.2009., James et al.2008., Athanasios et al.2008., Raphaël et al.2007., Julie et
al.2007., Michel et al.2007 ]

Since the obtained amount related to students' social growth who participated in handball exercise is in a acceptable level, we can understand that
handball as a gregarious sport. Brings development and higher students social growth. Having social developed people means to have men who can do their
affairs independently and under take their responsibilities in different affairs and in this are compatible with another people, groups and
institutions. Also can do healthy and beneficial relationship, combined with mutual respect. Such capability, allows the person that stable against in
daily life problem and don't down against them.
